carry(a,b,c) carry(a,b,c) {
result = a + b + c; // unsigned additions
return result[32];
cdc_decrement() If PSW.CDC == 7’b1111111 returns FALSE, otherwise decrements
PSW.CDC.COUNT and returns TRUE if PSW.CDC.COUNT underflows,
otherwise returns FALSE
cdc_increment() If PSW.CDC == 7'b1111111 returns FALSE, otherwise increments
PSW.CDC.COUNT and returns TRUE if PSW.CDC.COUNT overflows,
otherwise returns FALSE
cdc_zero() Returns TRUE if PCW.CDC.COUNT == 0 or if PSW.CDC == 7'b1111111,
otherwise returns FALSE
leading_ones(x) Returns the number of leading ones of ‘x’
leading_signs(x) Returns the number of leading sign bits of ‘x’
leading_zeros(x) Returns the number of leading zeros of ‘x’

return ((x > max_pos) ? max_pos : ((x < max_neg) ?
max_neg : x ));
suov(x,y) max_pos = (1 << y) - 1;
return ((x > max_pos) ? max_pos : ((x < 0) ? 0 : x));
sign_ext(x) Sign extension; high-order bit of x is left extended
trap(x) Instruction will take trap ‘x’
